It
would be interesting to research the idea of introducing oxygen
directly into the blood stream bypassing the lungs. That would enable
physicians to work on lungs off-line while a patient with pneumonia,
cystic fibrosis etc. could remain alive without breathing.
If
one has nearly complete blockage of lungs with pneumonia or jell
afterwards experimenting with using unconventional treatment such as
hydrogen peroxide delivered locally to burn up some of the insulting
substance might be enabled if the lungs were not needed for breathing
for a while.
Some
sort of portable rebreather that is designed to deliver and monitor
returning blood oxygen and other gas (levels) could be made to plug
in at some point of connection where it would replace lungs
temporarily, entirely if needed. I am unaware if the technology
exists already (it should), if it is feasible if it doesn't, or who
would invent it. Existing heart-lung machines might serve a similar
function. If the heart is healthy one might need only a synthetic
lung. It might better be reduced to just an oxygen delivery unit
without the lung-bag though, in the form of an efficient
rebreather/concentrator of scrubbed atmospheric oxygen. Then one
could walk about while the lungs are experiencing chemical-biological
cleansing and blood is being reoxygenated by a discrete unit-pack.
The
technology might be useful for manned space missions to worlds
without human-breathable atmosphere or if existing in an artificially
reduced metabolic state..
Good
luck.
